Everything LudeFill does

One document workflow, five capabilities. The convert tools run entirely in your browser; documents you save to your workspace are stored securely on our servers and encrypted in transit.

01Edit

Mark up any PDF without printing it

Add text, highlight, draw, white-out, and drop shapes or images straight onto the page, then flatten and download a clean file.

  • Text boxes, highlights, and freehand drawing
  • White-out and shape tools
  • Undo, redo, zoom, and page navigation

02Fill

Build fillable forms and complete them fast

Detect existing form fields or drag your own — text, checkboxes, radios, dropdowns, dates, and signature placeholders — then fill and save.

  • Auto-detect existing AcroForm fields
  • Drag-and-drop field builder
  • Save a filled, ready-to-send PDF

04Convert

Merge, split, and reshape PDFs in your browser

Combine files, extract page ranges, reorder and rotate pages, turn images into PDFs, export pages as PNGs, and re-save an optimized copy. These tools run entirely in your browser — files you convert here are not uploaded for processing.

  • Merge, split, organize, and optimize
  • Images to PDF and PDF to images
  • Runs client-side in your browser
